Pls. advise on correct scripting.
Using Acrobat XI Pro, Livecycle ES4
First, you should add spaces to your script to make it more readable.
Then you should check that you've used the exact naming of your fields (names are casesensitive).
I can see that the field is named Fill_Wt but in your script you've used fill_wt so I assume the other fields have use uppercase letters included.
